Description

Technical Field

[0001] The utility model relates to the technical field of woven bags, in particular to a double-layer woven bag. Background Art

[0002] Woven bags are made of plastic raw materials that are extruded into films, cut, unidirectionally stretched into flat wires, and then weft-woven to produce plastic products. Woven bags are mainly made of polypropylene bags and polyethylene bags; they are divided into bottom-sewn bags and side-sewn bottom bags according to the sewing method.

[0003] Publication number: CN207497222U discloses a high-strength woven bag, including a woven bag, which is woven horizontally and vertically by strips, the strips include polypropylene rings and nylon belts, the lower end of the woven bag is sewn to the outer side of the upper end of the bottom plate, the vertical shaft is movably installed on both sides of the movable plate through holes and grooves, and the insertion rod is movably installed in the middle of the vertical plate through a circular hole.

[0004] At present, the existing woven bags have the following disadvantages when used: lack of anti-collision mechanism, usually during the process of carrying and transporting, the woven bags are squeezed by external factors such as narrow environment, which easily causes damage to the materials stored in the bags, greatly reducing the stability and safety of the woven bags. To this end, we propose a double-layer woven bag. Utility Model Content

[0005] The main purpose of the utility model is to provide a double-layer woven bag, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A double-layer woven bag comprises an outer bag body and an inner bag body, wherein the inner bag body is connected to the outer bag body by sewing, a hollow portion is opened on the inner side of the outer bag body, an air cushion is connected to one side of the hollow portion by gluing, a buffer pad is connected to the outer side of the air cushion in the hollow portion by gluing, an inflation seat is arranged on one side of the outer bag body, and an air outlet end of the inflation seat is connected to the air cushion, and an elastomer is arranged in the inflation seat.

[0008] Furthermore, a one-way valve is arranged at the air inlet end of the inflation seat, a valve core is arranged at the bottom of the inflation seat, and the one-way valve and the valve core are connected to the inflation seat through a slot.

[0009] Furthermore, the buffer pad includes a buffer sheet and a fold.

[0010] Furthermore, the outer bag body and the inner bag body are both provided with a bending portion.

[0011] Furthermore, a storage groove is provided in the inner bag body, a lifting rope is provided on the outer surface of the outer bag body, and the outer bag body is connected to the lifting rope by gluing.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Through the arrangement of the outer bag body, the inner bag body, the hollow part, the buffer pad and the air cushion, the deformation caused by the inflation in the double-layer woven bag can be utilized to quickly form an auxiliary anti-collision structure, which is less likely to cause damage to the materials in the bag by external forces such as extrusion and collision. At the same time, the woven bag as a whole is more three-dimensional and stable. When storing and retrieving materials, the bag opening is less likely to be skewed to affect the operation. The structure is simple and compact, the cost is low, and it is easy to operate, and it is more stable and reliable to use.

[0014] 2. By providing the inflation seat, elastomer, one-way valve and valve core, the anti-collision structure can be quickly inflated by utilizing the elastic deformation generated by pressing, and when the woven bag is stored, the deflation operation will not affect the folding.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 , 2As shown in Figure 3, a double-layer woven bag comprises an outer bag body 1 and an inner bag body 2, wherein the inner bag body 2 is connected to the outer bag body 1 by sewing, a hollow portion 3 is opened on the inner side of the outer bag body 1, an air cushion 4 is connected to one side of the hollow portion 3 by gluing, a buffer pad 5 is connected to the outer side of the air cushion 4 in the hollow portion 3 by gluing, an inflation seat 6 is provided on one side of the outer bag body 1, and the air outlet end of the inflation seat 6 is connected to the air cushion 4, and an elastomer 7 is provided in the inflation seat 6.

[0022] The outer bag body 1 and the inner bag body 2 are both made of polypropylene.

[0023] Wherein, a one-way valve 8 is arranged at the air inlet end of the air-filling seat 6 , and a valve core 9 is arranged at the bottom of the air-filling seat 6 .

[0024] In this embodiment, Figure 3 As shown, the one-way valve 8 and the valve core 9 are used to control the inflow and outflow of air in the air cushion 4.

[0025] The buffer pad 5 includes a buffer sheet 10 and a fold 11 .

[0026] In this embodiment, Figure 4 As shown, the buffer sheet 10 and the fold 11 facilitate the folding and recycling of the woven bag, and the buffer sheet 10 is a sponge gasket.

[0027] Wherein, both the outer bag body 1 and the inner bag body 2 are provided with a bending portion 12 .

[0028] In this embodiment, Figure 1 As shown, the bending portion 12 facilitates the anti-collision structures on both sides to be pushed inwards for folding and recovery.

[0029] A storage slot 13 is provided in the inner bag body 2 , and a lifting rope 14 is provided on the outer surface of the outer bag body 1 .

[0030] In this embodiment, Figure 1 As shown, the storage slot 13 facilitates the storage of materials, and the lifting rope 14 facilitates the carrying of the woven bag.

[0031] It should be noted that the utility model is a double-layer woven bag. When working, the operator first manually presses the elastic body 7 in the inflation seat 6, and uses the deformation caused by pressing to draw external air into the air cushion 4 through the one-way valve 8 and the inflation seat 6. The deformation and the buffer pad 5 are generated by the inflation of the air cushion 4, and an auxiliary anti-collision structure can be formed on the periphery of the inner bag body 2, thereby reducing the impact caused by external extrusion and collision, greatly improving the stability and safety of the materials in the woven bag during movement and carrying. At the same time, it can also make the woven bag as a whole more three-dimensional and stable, greatly improving the convenience of material storage and retrieval. After use, the air cushion 4 can be deflated through the valve core 9, and then the bending part 12 can be folded inward from both sides, and then the outer bag body 1 and the inner bag body 2 can be folded, and the buffer pad 5 can be folded through the buffer sheet 10 and the crease 11 for storage. The overall structure is simple and compact, low cost and easy to operate, and it is more reasonable and stable to use.
